When the Iron Rusts

The child's breathing woke her.

Not Mared's breathing—the absence of it. The pause between inhale and exhale that stretched a half-second too long, the hitch in the rhythm that pulled Elowen out of sleep the way a hand pulls a woman from water.

She was on her feet before her eyes were open.

The hut was dark, the fire banked to coals, the air thick with the smell of willow bark and sour fever sweat. Mared lay on the low pallet by the wall, small and burning, her shift damp and twisted around her thin body. Five years old. Three days sick. A cough that had started in the chest and climbed into the throat and turned breathing into a struggle.

Elowen knelt. She placed her hands over the girl's ribs, an inch above the skin, and felt for the heat. It was there. Stubborn, concentrated, the body at war with something it couldn't name.

She pressed down. She felt the lungs working beneath the bone. The wet rattle. The labored, lurching rhythm.

She hummed. Low, steady, matching the child's breathing. The melody was older than the words the druids set to it. A tune the body recognized the way it recognized warmth or the voice of its mother. She had learned it from Brennus, who had learned it from his grandmother, who had learned it from the oak.

Under her palms, the heat began to shift. Moving downward, drawn through the child's body toward the earth beneath the packed-dirt floor, the way water is drawn through roots.

Mared's breathing steadied. The hitch eased. The rattle thinned.

Elowen held her hands where they were and kept humming until the coals dimmed and the first gray light crept through the gaps in the thatch. Her knees ached. Her eyes burned. But she did not move.

At dawn, the fever broke.

Mared opened her eyes. They were glassy, confused, but alert. She looked up at Elowen with the unguarded gaze of a child surfacing from deep water.

"There you are," Elowen said.

Mared's mother let out a sound—half sob, half prayer—and crossed the hut in two steps, gathering the child against her chest.

Elowen stood. She gathered her herbs: the unused poultice, the jar of meadowsweet salve, the strips of linen she'd brought in case the fever turned violent. Her hands were steady. They were always steady during the work. It was after that the shaking came.

She let herself out of the hut.

The air hit her like cold water. Sharp, clean, smelling of wet earth and pine resin and the faint green sweetness of moss. The camp was waking. Smoke rising from cook fires. Children splashing through puddles left by last night's rain. A dog barking at something in the trees.

She walked toward the river.

The path took her along the ridge where the soil was driest, past the huts and the drying racks and the stone mortar where she ground her herbs. She walked without hurrying. There was nowhere to hurry to. The rhythm of the camp was the rhythm of the day—meals to cook, animals to tend, children to watch, the sick to visit, the pregnant to reassure.

This was the work. Not the singing or the ceremonies or the trances at the Spring. This. The daily tending.

At the river, she found Rhiannon sitting on the flat stone by the ford, her feet in the shallows, her belly enormous beneath her loosened tunic.

"She kicked me in the bladder at moonrise and I have not forgiven her," Rhiannon said.

Elowen knelt beside her. She placed her hands on Rhiannon's belly. Head down. Good position. The baby shifted under her palms, a slow, rolling movement, a body turning in its own dark water.

"Two weeks," Elowen said. "Perhaps less."

"Promise you will be there."

"I promise."

She mixed a tea from dried yarrow and chamomile. She sat with Rhiannon while she drank it. She held her hand.

Then she stood. She had three more visits to make before midday. The bone-setter's wife. Old Nerys. The boy at the edge of camp with a cut foot going to rot.

At the central clearing, she paused.

Brennus was sitting by the communal fire, mending a fishing net. His fingers worked the knots with the patience of a man who had been doing this particular task for longer than most people had been alive. He was old—the villagers said impossibly old, though Elowen suspected he was seventy and had earned his mythology by outliving everyone who could contradict him. Deep lines in a face that had forgotten how to be soft. A nose broken twice and set once. Eyes the color of peat water, catching light only at the edges.

He did not look up as she passed. But he spoke.

"The ground was restless last night."

Elowen stopped.

"I felt it too," Elowen said. "In the hut. During Mared's fever."

"Not the fever. Something else." His fingers stilled on the net. "A vibration. Rhythmic. Coming from the south."

She waited.

"Iron on stone," Brennus said. "Stone on earth. They are driving stakes. Survey markers, if I had to guess. The pattern is too regular for construction." He resumed his work. "They are measuring."

"How far?"

"Three miles. Perhaps less. The Root carries sound differently through wet ground."

Three miles. The grove extended a mile in every direction from the Spring. The cleared fields beyond that—the land the families farmed, the pastures where the goats grazed—ran another mile before the scrubland began.

Three miles meant the edge of the scrubland.

"They will reach the fields by midsummer," Elowen said.

"Sooner, if they are legionaries. Romans do not stop for weather."

"What do we do?"

Brennus tied a knot. He held the net up to the light, inspecting it.

"We tend the grove," he said. "We mind the Spring. We do what keepers do."

"And when they arrive?"

He looked at her then. His peat-water eyes were steady.

"Then we will see what the earth asks."

He went back to his net.

Elowen stood in the clearing for a moment longer. The cook fires smoked. The children played. The sounds of the camp were the sounds of ordinary life—voices and footsteps and the clatter of wooden bowls.

Beneath it, if she listened, the vibration. Faint. Rhythmic. Getting closer.

She walked to the Spring.

The twelve oaks stood in their rough circle, branches woven into a living vault overhead. The water was still today, a mirror reflecting the canopy. She knelt at the edge and placed her hands flat on the surface.

Beneath her palms, the Root's pulse. Steady. Patient. Unchanged.

But today she felt something else. A tremor in the deeper layers, like a string tuned too tight.

Elowen closed her eyes.

The tug came immediately. South and east, toward the sound of iron on stone. Not a voice. Not a command. Just a pull, the way a current pulls—patient, constant, indifferent to whether she followed.

She opened her eyes.

She dried her hands on her tunic. She stood.

She did not follow the pull. Not today. Today there was a bone-setter's wife to see, and old Nerys with her tremors, and a boy with a cut foot, and a pregnant woman who needed to know she would not be alone.

But all day, as she ground herbs and mixed poultices and held hands and checked wounds, she felt it. The pull. South and east, every time she reached a fork in the path.

Getting closer.
